Again, mupad gives an exact solution – but it’s not very easy to visualize what the solution looks like! If

we substitute numbers we can plot it

Of course, not all differential equations can be solved exactly.

Mupad now gives no solution. It is possible for Mupad to compute a numerical approximation, but in

most cases it is more straightforward to use MATLAB if an analytical solution cannot be found. We

will use MATLAB exclusively for this purpose in this course.

11. Vectors and Matrices

Finally, we’ll take a look at Mupad’s functions that deal with vectors and matrices. Strangely, vector and

matrix manipulations are more cumbersome than most of Mupad’s capabilities – even doing a trivial

thing like a dot product is a chore. Here are some basic vector/matrix manipulations.
